Using a 1/10th of a second interval is rather anti-social.
I know we rate-limit ICMP traffic down, and such a
short interval would be detected as attack traffic,
and treated as such.
...
For what it is worth, I used to think the same, until I saw several 
providers themselves suggest that 1000 packets should be sent, with 
the 0.1 s interval.  So, this is considered normal and appropriate 
nowadays.

Disagree. You are of course free to use whatever rate you want between
your own end points. If you want a response from routers on the public
Internet, you should *expect* this to be rate limited. I certainly
don't think that a 0.1s interval is appropriate - and configure control
plane policing on "my" routers accordingly.
